General information

During the game, the current Map is displayed by the main Viewport, which is the bottom-most widget in the WindowContainer. Aside the viewport, the window container keeps track of all the Windows displayed during the game. It is the top widget for Guichan.

A Map is composed of several layers of Images (tiles), a layer with collision information and Sprites. The sprites define the visible part of Beings and FloorItems, they are drawn from top to bottom by the map, interleaved with the tiles in the fringe layer.
